This TCP/IP specific function of type DINT calls the function send of the operating system in order to send the data which are buffered at the socket.

The function will return the number of sent bits. If the socket has been “gracefully closed” , 0 will be returned, otherwise 1.

Variable Data type Description

(corresponding parameter e.g. in Win32: s)

pbyBuffer DWORD

Address of the buffer from which the data should be send

(corresponding parameter e.g. in Win32: buf)

diBufferSize DINT

Size of the buffer from which the data should be send

(corresponding parameter e.g. in Win32: len)
